get_callees
Retrieve all functions called by a specific function in IDA Pro using its address. Simplify reverse engineering by identifying callee functions efficiently.

Implementation Reference
- Helper function implementing logic to find all unique callees (functions called) from a given function address by scanning call instructions.
